Mr. al-Bashir, 75, questioned in court for the first time during his trial in Khartoum, said that he had received $25 million from the Saudi crown prince, Mohammed bin Salman, but that he had not used the money for private purposes.

The authorities found millions in foreign and domestic currency stockpiled at his home after he was arrested.

A lawyer for Mr. al-Bashir said that his client denied the charges of corruption and money-laundering, and that witnesses for the defense would be presented at the next hearing.

The deposed leader has yet to face charges in relating to the killing of protesters during the popular uprising that led to his military ouster after three decades in power.

Mr. al-Bashir is also wanted by the International Criminal Court on charges of war crimes and genocide linked to the Darfur conflict in the 2000s.

Many Sudanese had hoped that Mr. al-Bashir’s ouster would end any link to his administration, during which Sudan endured revolts and the United States imposed sanctions. In August, Sudan’s military and civilian leaders signed a power-sharing deal to jointly run the country for three years until elections could be held. A transitional government run by civilians is set to assume power on Sunday.

But most Sudanese say the revolution is incomplete. Many of the generals who led a brutal military campaign in the western region of Darfur in which up to 300,000 people were killed are expected to hold senior positions in the new government.
